Dams can be damaged and may require repair

Explanation:

This is imperative to  provide    needed supports and maintenance  for the aging dams,with capacity of up to 11,000. This dams were created as far back as 1948.Therefore the programme was geared towards effective re-habitation  for  maximum efficiency.

This repair programmes was termed Dam Rehabilitation Programme.And the secretary of Agriculture was given the authority to ensure effective execution of the programme.

In  the state of Virginia,a  total of 150 dams  were part of the government landscape through the rehabilitation programme, and 11 of these have been well studied. .Todd Lake,Robinson Hallow, Lake Barton are some of these examples.

why is not recommended to use antibiotics often

Answers

Answer: It may cause the bacteria to become resistant to them and one they are resistant then the antibiotics are ineffective against the bacteria. It is then more dangerous since new antibiotics will need time.

Explanation:

Explanation:

If you take antibiotics for the wrong reason(s) or if you take them too often it can change bacteria so much, that antibiotics have a reduced effectiveness against them, or stop working against them all together.

The so called "bacterial resistance" or "antibiotic resistance" is a real thread to humans. Some bacteria have turned out to be resistant to even the most powerful antibiotics available. Antibiotic resistance is a growing problem.

Suppose you get infected with such resident bacteria, it means there is no longer an effective treatment by using antibiotics.

*EXTRA*

If left "un treated", the bacteria can grow, more or less, with unlimited exponential growth. In such scenarios, any "simple" bacterial infection, could turn out to be fatal.

Often the biggest problem is the lack of time to find out exactly what type of bacteria is making the patient ill. Because there are so many different bacteria, it is impossible to tell what is the right one without deduction and, that takes time (to grow visible cultures in the laboratory). Sometimes a patient might be already critically ill, in such cases, the doctor would want to start the treatment immediately, which could mean they HAVE TO start admitting a broad-spectrum antibiotic, to hopefully battle that group of different bacteria, which hopefully included the one that is making the patient ill. But if that specific bacteria turns out to be resestant, then that poses a very serious problem. Possible a fatal one, since the time is up, and the bacteria keep growing in numbers, roughly doubling in numbers every hour...

Answers

I think the answer is B.

The essence of the experiment was that  it showed that biological molecules could have formed in a similar way.

What was the experiment of Miller and Urey?

The experiments of Miller and Urey were the first step in trying to prove the idea tat life originated from simple biological molecules.

Though the life forms did not form from the gases that were used, but the biological molecules did form. Thus, the essence of the experiment was that  it showed that biological molecules could have formed in a similar way.

The level of organization displayed by both Arachnoidiscus ehrenbergi and the human stomach would be the cell.

Since it has already been established that Arachnoidiscus ehrenbergi is a single-celled organism, it can only exhibit a cellular level of organization.

The human stomach, in a similar vein, is made up of different cells. One group of such cells are secretory epithelial cells. They include the mucous cells, parietal cells, chief cells, and so on.

Thus, Arachnoidiscus ehrenbergi and the human stomach have the capacity to exhibit a cellular level of organization.

How would driving from Boston (near sea level) to summit of Mt. Washington affect the rate of oxygen exchange in your lungs? Explain in 1-2 sentences plz

Answers

Answer:

The rate of oxygen exchange in the lungs decreases, outstandingly while diving from Boston (near sea level) to summit of Mt. Washington

Explanation:

At near sea level, Boston, where there is sufficient dense air and plentiful supply of oxygen, the rate of breathing and oxygen exchange in the lungs is at normal levels

At the height of 6,288.2 feet, which is the height of the summit of Mt Washington, the lung does more work to extract the oxygen from the air present which is less dense and contains less oxygen than the air at sea level such that a larger volume of air is required to supply the amount of oxygen the body requires

Therefore, the rate of oxygen exchange in the lungs decreases, outstandingly while diving from Boston (near sea level) to summit of Mt. Washington.

A plant has two alleles for color. The red allele is recessive, and is represented by q. The purple allele is dominant, and is represented by p. If 59 of 100 organisms are red, what is q? P^2 2pq q^2=1

Answers

Answer:

q is 0.7681

Explanation:

The red allele is recessive, and is represented by q.

If 59 of 100 organisms are red meaning the frequency of the recessive genotype of red is 59/100 = 0.59 represented by q².

Thus q would be to find the square root of q². Where q is the frequency of the recessive allele in the population

Thus, q = √q² where q² = 0.59

q = √0.59

q = 0.7681
